My research revolves primarily around augmenting the availability and dependability of intricate systems, those which hold paramount importance in business and safety-critical operations. The principal methodological approach I employ for this undertaking is probabilistic reasoning, with a focus on utilizing Bayesian networks in an array of manifestations, such as dynamic and decision networks.

The primary challenge I address pertains to the component level, which necessitates the capture of changes at a granular level. The objective is to emulate these alterations at a more comprehensive level, propagating them accordingly, with the ultimate aim of predicting the potential ramifications at a system-wide scope.

In addition, my research extends beyond the solitary functioning of individual components. I give equal emphasis to the interaction dynamics among various system components, scrutinizing the ripple effects instigated by alterations in a single component on the functionality of its counterparts.

In essence, my academic pursuit is a holistic exploration of system reliability, taking into account both individual component behaviors and their interactive dynamics within a complex system.
